FREDERICK C. SCHOFIELD, OF SALEM, VIRGINIA, ASSIGNOR 'IO COMAS CIGARETTE MACHINE COMPANY, OF SALEM, VIRGINIA, A CORPORATION OF VIRGINIA.

. COUPON OR CARD FEEDING DEVICE.

Application filed August 22, 1919.

T 0 all 20. 2 cm it may concern Be it known that I, Fnrnnnici; C. SonormLo, a citizen of the United States of America, and a resident of Salem, in the county of Roanoke and State of Virginia, have invented certain new and useful Improvements in Coupon or Card Feeding Devices, oi which the following is a specification.

This invention relates to improvements in coupon or card feeding devices in which a feeding device is arranged to contact with the bottom card of a stack of cards contained in a suitable receptacle to feed said cards forward between the delivery rolls, areversely acting roll being preferably provided to prevent the feeding of two cards should more than one card be accidentally fed forward at the same time.

The invention consists in the construction and arrangementof parts hereinafter described and then definitely claimed.

In the drawings which represent the prof erable, but not necessary, embodiment of my invention:

Figure 1 is a side elevation of a coupon or card feeding device made in accordance with my invention parts being broken away in order to show the'interior construction.

Fig. 2 is an end elevation of the same.

Fig. 3 is a perspective view of a crank shaft detached.

Fig. 1 is an end elevation viewed from the opposite end to that shown in Fig. 2.

Fig. 5 is a perspective view of the rocking head and needle, detached.

Figs. 6 and 7 are sectional views showing the different movements of the device.

Referring now to the details of the drawings by numerals: 1 designates a card receptacle which maybe of any desired form. preferably open at the bottom, as illustrated in Figs. 6 and 7. Under the card feeder is arocking head formed of two main members 2 and 3 (see Fig. between which are secured needles at (similar to those used on a graphophone) the parts 2 and 3 being adapted to be secured together by a screw as illustrated in Fig. 6, to clamp the needles 1 between them. In a manner to be hereinafter described, the needles a are adapted to move the card on the bottom of the pile to the left as viewed in Fig. 6 until its front edge projects between delivery rolls 5 and 7, these rolls having gears 11 and 13 on their Specification of Letters Patent.

ends by which they are simultaneously driven, the upper gear 11 preferably having one or two teeth more than the lower gear in order to cause a slight difference of pe rlpheral speed of the delivery rolls 5 and 7 to keep them free from accumulated dust and d1rt from the cards. Just in advance of the upper delivery roll 5, and between said roll and the card receptacle 1, is supported a rubber covered roll 15 on the end of which is a gear 17 meshing with the aforesa d gear 11. This construction causes the delivery roll 5 to rotate in an opposite direction from that of the rubber covered roll 15. Underneath said rubber covered roll 15 is an anti-friction roll, 16 which is located at just the proper height to permit the cards to move over the same with as little friction as possible, a supporting plate 18 being provided between said anti-friction roll 16 and the delivery rolls 5 and 7. It is desirable that there should be just sufficient space between the rubber covered roll 15 and the anti-friction roll 16 to permit of the passage of a single card and, therefore, should two cards happen to be fed at once, the rubber covered roll 15 which is rotating in an anti-clockwise direction will prevent the upper of the two cards from being fed through to the delivery rolls 5 and 7 In order that the rolls 15 and 16 may be adjusted with respect to each other, I support the rub ber covered roll 15 in movable bearings adjustable by the set screws 12 passing through a yoke 14. At the other end of this yoke are springs 10 which bear upon a yoke 8 and make certain that the upper delivery roll 5 shall bear with sufficient pressure against the lower delivery roll 7 On the end of the shaft to which the lower delivery roll 7 is secured, I attach a crank disk 9, the wrist pin 20 of which is connected by a connecting rod 22 with the cross head 23 hereinbefore referred to by means of an eccentric shaft 19. One end of this shaft passes through the aforesaid connecting rod 22 and is moved thereby, and the other end of said shaft passes through bearings 24 projecting upwardly from a slide 26, the eccentric part of the shaft between said bearings 24 passing through the lower part 2 of the rocking head 23. The slide 26 therefore acts as a support for the rocking head 2 and 3 and when the latter is moved in one position, a lug 27 on the part.

2 of the rocking head contacts with the front end of the slide 26 and prevents further movement, while, when the rocking head is moved in the other'direction, the lug 27 moves away from the slide and the bottom of the rocking head 2-3 contacts with the slide and prevents further movement in the opposite direction. Underneath the slide 26 is a spring 28 having on its upper surface a piece of leather 29 to contact with the lower end of the slide and frictionally hold said slide in any position to which it has been moved as will be hereinafter explained. The construction ofthe parts just described is such that, as the crank disk rotates with 1 the lower delivery roll 7 the connecting rod 22 moves the slide and the rocking head'back and forth under the card receptacle 1. It will be observed that during the rotation of the crank disk 9 before the connecting rod 22 pulls the rocking head forward the crank shaft revolves about45 until the lug 27 moves from the position shown in Fig. 7 to the position shown in Fig. 6 to contact with the front end of the slide26, at which time the needle points have engaged the lower card and from now on the whole structure moves forward, the card being carried along, until after the crank disk passes over the center and drives the connecting rod back, the rocking head remaining stationary owing to the friction caused by the piece of leather 29 being held in contact with the bottom of the slide 26 by the spring 29 until the crank has revolved back through 45 and then moves the rocking head into the position shown in Fig. 7, this action dropping the needles away from thecard so as not to scratch or scar the bottom card in the rearward movement. If, for any-reason, the needles should not feed the bottom card, I have provided thepart 3 of the rocking head 2-3 with an offset 30 (see Figs. 5 and 7) which will engage the rear end of the bottom card and move it until the front end of the card is engaged by the delivery rolls and 7, asthe crank disk rotates to draw the connecting rod 22 and the rocking head 23 along under the bottom of the card receptacle. 1 V

I have described the operation of my coupen and card feeder at the same time that I have described the various parts, and hence it is believed that further description of the operation is unnecessary. However, I desire to point out the fact that one end of the rocking head, as viewed in Fig. 6, is so constructed that it will contact with the bottom card before the needles will penetrate entirelythrough the card, and that further rotation of the crank diskwill draw the rocking head and its needles forward to feed 7 the bottom card andthat when the rockinghead and its needles reach the position where the delivery rolls 5 and 7 receive and positively feed the card forward, the wristpin 20 begins its downward movement and thus causes the rocking-head to swing down and permit the needles to descend with respect to the card. 'This moves the needles to and forward by the upward movement of the wrist-pin 2O pulling upon its connecting-rod 22, as shown in Fig. 6.

It will be obvious that changes and modifications may be made in my invention without departing from the spirit thereof, the scope of which is set forth in the appended claims.
